Poem

🐰 I hopped through metrics, tidy and bright,
Added counters, reordered by light,
Duplicates cleared with a nimble leap,
Docs now humbly count what they keep,
A rabbit's cheer for monitoring neat 🥕

In `@administration/monitoring.md`:
- Line 211: The Unit value for the metric `fluentbit_hot_reloaded_times` is
incorrect — change the Unit column from `seconds` to a non-time unit such as
`times` or `count` in the table entry for `fluentbit_hot_reloaded_times`; keep
the name and label (`hostname`) and the type `counter` as-is to reflect that it
counts discrete hot-reload events rather than measuring duration.
